please give us a run down of your set-up, what stage of growth, type of grow medium, nutrients used, etc etc and we might be able to offer a helpful opinion

ebb n flow setup... nutes are DNF Bloom A & B. with hygrozyme and DNF Gold.
Ph is always set at 5.6 and raises to 6.1 - 6.2 , then i drop it back down a bit before i change the resevoir.
The res gets changed every week, and the water sits 24 hours before use.
The plants are about 2 weeks into flower, and the deficiency is showing on the oldest leaves first and working its way up the plant.
hope this can help
p.s - i grow in 4 inch rockwool cubes surrounded by hydroton in my tray and my temps are always 75-79 F and my RH % is always 30-60%

I have no experience with hydroid....hopefully one of the members with extensive experience in this area can offer some help.
one thing you didn't mention was the concentration of ferts used...do you measure this with a EC or PPM meter or just guess it?

could very well be. the coloration is not familiar to me, but the leaf curl is. am i seeing correctly that the leafs are curled upwards around the tips especially? looks a lot like Mg. Def. Add epsom salt if you're using tap water, or Cal-Mag (a botanicare nutrient product) if you're using RO water.

I've never seen the leaf coloring, but based on the curving and info you gave I think it's magnesium deficiency. Used to happen to me every grow til I started using Cal-Mag.

Hey Queso, have you figured out what the problem is? It might be a magnesium deficiency but it doesn't really look like one.
Although I have never had a problem as bad as yours I reckon it might be a boron deficiency.
GH sell a nutrient corrector called Bio Essentials. That would sort your problem if it is that.
